pressed with a short median longitudinal impressed line. Forceps of 

 female less than half the length of the abdomen, moderately stout, 

 simple, nearly horizontal but slightly curved, the convexity down- 

 ward, depressed trigonate with a superior ridge, tapering regularly, 

 straight on the basal two-thirds and then gently and regularly in- 

 curved, the tip bluntly pointed; inner edge with a superior small 

 basal bifid tooth, and on the inferior edge slight denticulate sinuations 

 on the basal half. Length of body, 8.25 mm.; of antennas, 4 mm.; 

 of tegmina and wings, 3.6 mm.; of hind femora, 1.75 mm.; of forceps, 

 2.1 mm. 1 ?. Waco, Texas; collected by G. W. Belfrage on Feb- 

 ruary 24 th. 



A slender, graceful and very dark colored species, nearly related 

 to the almost apterous L. Burgessii. Probably the male forceps of 

 the two species will prove to be somewhat similar. 



Orthoptera from the Island of Guadalupe. 

 By Samuel H. Scudder.] 



The four Orthoptera described below comprise all the species that 

 were collected by Dr. E. Palmer during a recent visit to the Island 

 of Guadalupe, off the coast of Lower California. Two of the spe- 

 cies, as will be seen, also occur in the southern part of California, 

 and one of them also in Mexico ; the third Acridian will very proba- 

 bly be discovered there, but the Gryllus, which appears to be more 

 nearly related to G. peruvianus Sauss., than to any other species, will 

 not improbably prove indigenous, and is remarkable for the brevity 

 of its tegmina and wings. None of them appear to have been de- 

 scribed. 



Gryllus insularis. Of medium size. Head shining black, 

 tumid, with a broad shallow depression between the lateral ocelli and 

 just above the median ocellus; antennas nearly twice as long as the 

 body, black, growing a little testaceous from end of the basal third 

 toward the tip; middle of mandibles and galea more or less tinged 

 with reddish; palpi blackish brown. Pronotum black, shining, nearly 

 twice as broad as long, with a slight median impressed line more 

 distinct in front; front border straight, or scarcely angulate in front, 

 the angle opening forward; hind border straight, or slightly full in 

 the middle, very delicately marginate, laterally with a few curved
